摘　　要：针对传统PID控制难以保证导弹在大空域飞行中保持良好动态性能的问题,提出一种基于广义最小方差自校正控制律的PID控制算法(GMVST-PID)。该算法在递推估计被控对象参数的基础上,将自校正思想用于PID控制参数的实时在线自整定,提高了导弹时变模型控制系统的稳定性、适应性和鲁棒性。仿真结果表明,GMVST-PID控制器具有较强的抗干扰能力和快速的响应能力。In order to solve the problem that traditional PID control can not retain a good dynamic performance in the application of anti-air missile, a PID control algorithm based on generalized minimum variance self-tuning control law （GMVST-PID） was designed. Based on recursive estimate missile＇s parameters, the self-turning theory was used to calculate the PID parameters on-line at real time. This scheme improves stability of system and also enhances adaptability and robustness of system. The result of simulation shows that the GMVST-PID controller has better anti-jamming capability and quick response.
